1. Intended Use and Field of Application
This product is intended
for calibratable volumetric metering using turbine gas meters and for non-calibratable volu-
metric metering using quantometers of
– ammablegases:naturalgas/towngas/propane/butane,
– non-ammablegases:air/nitrogen/inertgases
– and is suitable for use in potentially explosive atmospheres of Category 2 (Zone 1) of Class
EX II 2 G c IIC T4.
Othereldsofapplication/mediaonrequest.
Thepermittedgasandambienttemperatureistm=-25°Cto+70°C,unlessotherwisespecied
on the main plate (index plate).
The storage temperature is -25°C to +70°C.
The meters are suitable for mechanical ambient conditions of Class M1 of the Directive. For
meterswithanencoderindex,ClassE2forelectromagneticambientconditionsalsoapplies.
This product is not intended

The flow through the meter must be free of vibrations/pulsations in order to avoid measuring errors.
Compliancewiththespeciedoperating and ambient conditions as indicated on the type label
is absolutely essential for safe operationofthemeterandadditionalequipment.
The gas may not contain suspended particles > 50 µm.In addition, the gas must be dry.
Otherwise,themetermaybedamaged.

4. Staff
These Instructions are aimed at staffwhohaveadequatespecialistandtechnicalknowledge
(inGermany,forinstance,inaccordancewithDVGWCodesofPractice492and495orcompa-
rable technical regulations) on the basis of their training and experience in the sector of energy
and gas distribution.
Attention: incorrect use can be fatal!

6. Installation / Connection
Warning! Never clean the plastic cover of the index with a dry cloth owingto the risk of ex-
plosion resulting from electrostatic discharge! Please only ever use a cloth that has been
adequatelymoistenedwithwater!
Before installationpleaseensure:
– that the protective caps and/or plastic sheeting is or are removed,
– that the meter and accessories have been inspected for transport damage and
– thattheaccessorieshavebeencheckedforcompleteness(e.g.plugconnectors,oilforinitial
lling).
